HOUSTON (AP) - A college campus in Texas is on lockdown amid reports of a shooter on campus.

Lone Star College System issued an alert on its website Tuesday telling students and faculty on its Houston-area campus in north Harris County to take immediate shelter or avoid the campus. Spokesman Jed Young says there are reports of a shooter.

Aerial footage from local television stations shows emergency personnel attending to some people on stretchers and at least one being taken into an ambulance. Others can be seen running from a building led by officers.

The Harris County Sheriff's Office says it has no immediate details.
